Russian tech giant Yandex's data center in Sasovo burned out from the inside, a Ukrainian OSINT analyst wrote on 22 October. On cloud-free satellite images, he saw almost no significant holes in its roof. Ukrainian drones hit the site overnight on 8 October.

Sasovo was the first strike on a data center in Russia. It came two weeks after Russia destroyed data centers in Kyiv. Drones then hit Yandex sites in Vladimir and Kaluga, a Sber data center, and a VK data center near St. Petersburg, which VK acknowledged. In occupied Donbas, monitoring channels reported hits on buildings housing telecom operators.

What the analyst sees

The analyst, who goes by Harbuz, runs the Ukrainian OSINT channel Dnipro Osint. His roof reading comes from the images. His interior claim comes from what he called available information: he wrote that a fire broke out inside and put part of the equipment out of action.

In an earlier post, Harbuz wrote that a third of the data center had burned out. In the new one, he writes that the building burned out from the inside. He does not say whether he revised the earlier figure.

Russian outlet Agentstvo studied Airbus images from 12 October. It found damage on about a third of the building. Unlike Harbuz, though, Agentstvo described a blackened western roof with damage resembling holes.

What Yandex says

On 8 October, Yandex stated that the attack caused a fire and forced it to suspend operations at the site, which hosts tens of thousands of servers, Reuters reported. Yandex Cloud and the Disk and Documents services that run on it ran with major disruptions that morning, Russian outlet The Bell reported.

Later that day, the company stated: "The scale of the damage to the infrastructure is still being assessed. For the moment, we cannot confirm whether it is possible to restore the data centre equipment in Sasovo." Two of Yandex's three supercomputers, used to develop its AI model, are housed there.

The same day, journalists asked Ukrainian President Volodymyr Zelenskyy whether Ukraine was targeting Russian data centers. He did not refer specifically to the Yandex strike, Reuters noted, but said: "We always respond in mirror-like fashion."

Denmark will guarantee a loan to the Danish subsidiary of Fire Point, the Ukrainian maker of Flamingo cruise missiles, the Danish Business Ministry announced on 21 October. The financing will run through EIFO, Denmark’s state export and investment fund.

Ukraine uses its Flamingo missiles to strike defense plants deep inside Russia as Moscow continues its full-scale invasion. Fire Point broke ground in December 2025 on a plant in Vojens, southern Denmark, to make solid fuel for the missiles. The project has since grown far more expensive. In August, CEO Iryna Terekh said its estimated cost had risen from €50 million to above €150 million, calling the figure “very rough.” The war, meanwhile, stands in the way of Fire Point borrowing on ordinary terms in Denmark, the ministry said. That is why the Danish state is guaranteeing the loan.

What Denmark is putting up

The guarantee covers 750 million Danish kroner, or about $112.6 million, Reuters reported. Terekh said in August that the plant’s launch had slipped to late 2027. The ministry called the deal another big step toward starting production. However, Ukrainian outlet Defender Media noted that the statement does not say directly that the loan will fund the plant.

EIFO chief Peder Lundquist said the fund is involved in nearly 40 projects linked to Ukraine. Business Minister Martin Lidegaard said hosting a Ukrainian defense company brings Denmark knowledge, production, and partnerships. Europe’s security and freedom, he added, start in Ukraine.

Better shielded from Russian strikes

Defense Minister Jeppe Bruus said Denmark was the first country to decide to let a Ukrainian defense company set up on its soil. Production outside Ukraine, he argued, is better protected from Russian attacks. He added that Fire Point’s presence opens cooperation that could give Denmark access to technologies developed in wartime.

Denmark first said in September 2025 that Fire Point would make long-range missile fuel on Danish soil. Since then, the company has signed deals with more than a dozen European firms for FREYJA, an anti-ballistic project. It could reduce Europe’s long-term reliance on scarce US-made Patriot interceptors. Fire Point aims for a first ballistic missile intercept with it by mid-2027.

Ukrainian drones struck St. Petersburg’s oil terminal, a fuel depot, an Ozon distribution center, and a VK data center overnight, setting off fires across the city, monitoring channels reported. Russian outlet Meduza called it apparently the largest attack on the city and Leningrad Oblast since the war began. Russian officials acknowledged fires, damaged homes and substations, and power cuts.

Russia keeps fighting along the front while bombarding Ukrainian cities and the grid behind it. Ukraine’s long-range drones, in turn, target the oil exports and logistics that fund and supply that war, and Russia’s Baltic oil ports have been hit repeatedly this year. St. Petersburg is a symbolic place: Russia’s so-called second capital and Putin’s hometown.

Oil terminal and fuel depot on fire

Ukrainian forces struck the Petersburg Oil Terminal with FP-1 drones, starting a fire, Ukrainian drone maker Fire Point said. The company described the terminal as one of the region’s largest, handling 12.5 million tonnes of petroleum products a year, including for export.

St. Petersburg Governor Aleksandr Beglov acknowledged fires at the terminal and in four city districts, adding that Pulkovo airport had restricted flights. By morning, firefighters were still battling blazes at the terminal, the Ruchyi oil depot, and industrial warehouses in the Kolpinsky district, he wrote. He claimed one person was killed and five injured. Ukrainian monitoring channel Exilenova+ reported that the Ruchyi depot had been burning since the night.

Ozon hub, VK data center, and a bridge

An Ozon distribution center in Kolpinsky district caught fire after the attack, the company said, Russian independent outlet Astra reported. Astra’s open-source intelligence analyst described it as one of Ozon’s busiest fulfillment centers in northwestern Russia, covering up to 79,000 m².

FP-1 drones also hit a VK data center in Novosergiyevka, Leningrad Oblast, causing serious damage, Fire Point said. VK acknowledged a drone attack on the site but claimed its services were working normally. Leningrad Oblast Governor Aleksandr Drozdenko claimed air defenses downed 145 drones over the oblast alone. He acknowledged damage to the data center’s transformer equipment and warehouse complex, and minor damage to the Vostochnaya substation. Two other substations in Yanino went offline, cutting power to about 20,000 people, he said.

A drone also hit the cable-stayed bridge over the Korabelny fairway, part of a toll highway linking the city’s north and south, Exilenova+ reported, adding that the extent of the damage was still being clarified. The channel also reported a fire near a Russian Aerospace Forces radar company outside the village of Kaporskoye.

To reach St. Petersburg, Ukrainian drones had to cover 1,000 km across four Russian regions guarded by air defenses and electronic warfare, said Serhii Beskrestnov, adviser to Ukraine’s president on defense technology.

“And these are not cruise missiles with special systems, these are drones that fly at speeds of up to 200 km/h,” he wrote.

Strikes resume after a one-sided truce

The same night, Russia hit Ukraine’s grid again, and Ukrainian President Volodymyr Zelenskyy counted 76 Russian strikes on energy since the ceasefire was announced. US President Donald Trump declared the truce on 11 October. Ukraine paused its refinery strikes for three days at Washington’s request, but Russia struck a Kharkiv power plant within hours and kept hitting the grid. Zelenskyy then said Ukraine was resuming strikes on Russian oil and would stop again only in exchange for more US interceptors for its Patriot systems. Trump called the renewed strikes “a disgrace” and said he found Zelenskyy “more difficult to deal with than Putin.”

Ukraine has hit the St. Petersburg area before. In July, drones set fire to Wildberries warehouses near the city. In August, Ukraine began striking Ozon hubs, starting in Samara Oblast. The hubs move dual-use goods such as electronics and drone components.

Ukraine’s drone strikes on Russian tech giant Yandex thinned out social media bots, Ukrainian President Volodymyr Zelenskyy said on 12 October. Network data do show Yandex’s automated traffic collapsing after the strikes. Disinformation researchers say that traffic is search crawling, not trolls. A Ukrainian social media monitor told Euromaidan Press its own data show no clear drop in bot activity either.

Russian influence operations are a live threat to European votes. In August, the Matryoshka network fabricated news clips aimed at Sweden’s general election. German and French authorities flagged the same network targeting Germany’s local votes and French presidential hopeful Gabriel Attal. A way to switch such networks off would hand allies a new tool, which is why the claim needs testing.

The president’s claim

Addressing the Warsaw Security Forum by video link, Zelenskyy said that once Ukraine began answering Russia’s operation against Ukrainian data centers and its strikes reached Yandex, many social media platforms suddenly became a little easier to breathe on.

Many people noticed less hatred, discord, and provocation because there were fewer bots, he said. It was quite clear where those bots came from, he noted. Their disappearance once Yandex went down proves again that Europe is not the source of the problems, he added.

Lithuanian Prime Minister Mindaugas Sinkevičius said at the same forum that allies should ask Zelenskyy to strike more data centers in Russia, answering a question on how to protect their elections from interference.

Three data centers in four days

Drones first hit Yandex’s data center in Sasovo, Ryazan Oblast, on 8 October. Yandex said it shut the site down completely. The next day, a strike on its Kaluga site completely disabled several modules, the company said. Yandex calls Kaluga its largest data center, Russian science outlet T-Invariant noted.

Ukrainian drone maker Fire Point said its FP-1 long-range drones carried out that strike.

After the first strike, on Sasovo, a source at Yandex summed up the mood for The Bell: “Things are rotten. We keep working.”

Overnight on 11 October, drones hit the third site, in Vladimir. Yandex said it fully halted that data center too. Vladimir Oblast Governor Aleksandr Avdeev acknowledged an attack on “infrastructure” near the city. It started a fire and cut power to two substations serving 5,000 residents, he claimed.

What the traffic data show

Automated web requests from Yandex’s network fell to 0.4% of their two-week peak after the third strike, Cloudflare Radar data showed, Cybernews reported. That chart counts automated requests to websites, mostly from Yandex’s own search crawlers. It does not count social media posts.

The chart “has nothing to do with social media,” the Russian opposition analysis group Antibot4navalny wrote.

Russia’s overall bot traffic last week looked much like any other week. Yandex’s own figure began recovering on Sunday. Covert troll farms usually hide behind residential proxies, hacked devices, virtual private networks (VPNs), and Western cloud providers, the outlet added.

What Ukrainian social media shows so far

Yevhen Luzan tracks Ukrainian social media sentiment as an analyst at the Ukrainian nonprofit CAT-UA. Its daily reviews sample about 500 random posts. On 11 October, that sample showed an unusually small share of posts criticizing Ukraine’s authorities, he told Euromaidan Press. Accounts showing signs of bot activity made up only a few tenths of a percent of that criticism. That is within the margin of error.

The same day, though, US President Donald Trump’s deal for Russian diesel supplies dominated Ukrainian feeds. Luzan said a rally-around-the-flag effect could explain the shift, as outrage at Washington crowded out domestic stories.

“To state it definitively and draw a cause-and-effect link from this correlation would be too bold,” he said.

Across the wider pool of about 10,000 daily mentions, CAT-UA sees no significant drop in posting activity in recent days. The curve shows only the usual rises and dips around the start and end of the week, Luzan said.

“For now, even a hypothetical drop in bot farm activity dissolves entirely in the natural fluctuations of the information space,” he said.

How a crawler chart became a bot story

The claim that Russian social media bots fell by half is unproven and built on a misread chart, disinformation analyst Joohn Choe concluded in a fact-check. It traces back to an 8 October post by security researcher Jeremiah Fowler. That post said Russian bot traffic had dropped to 49%. On 11 October, radio reporter Jamie Dupree spread it on X. Tom’s Hardware then ran it under a headline calling the crawler traffic “Russian disinformation bot traffic,” wording it has since changed.

Ukrainian military analyst Tatarigami claimed that Texas separatist accounts with identical “Veteran, Christian, Father, MAGA” bios had gone quiet. He said Quebec separatists and Polish anti-EU accounts went quiet alongside them.

Polish military analyst Jarosław Wolski claimed that AfD’s online support fell 56%, posting a chart without naming its source. Another X user said “Polish” bots had vanished.

German radar maker Hensoldt has signed a memorandum with Ukraine's Defense Ministry for more large-scale radar deliveries, the company said on 5 October. Ukrainian defense outlet Defense Express reads it as a step toward fitting Hensoldt's TRML-4D, already in Ukrainian service, into FREYJA, a planned shield against ballistic missiles.

Ballistic missiles remain the hardest threat in Russia's air war. After Russia's overnight barrage on 7 October, Ukrainian President Volodymyr Zelenskyy said Ukraine is still searching daily for Patriot missiles. The only other system Ukraine can use against them is the Franco-Italian SAMP/T, which fires Aster 30 interceptors made in small numbers. That gap is why Fire Point is reworking its FP-7 missile into a Patriot-like interceptor. Such an interceptor still needs radars to find its target first.

A memorandum signed during Merz's visit

Hensoldt CEO Oliver Dörre signed the document on the sidelines of German Chancellor Friedrich Merz's visit to Ukraine. Beyond deliveries, it covers further development of radar capabilities. The partners will also study options to deploy and jointly operate TRL-4D LR long-range radars. Hensoldt said this expands cooperation already agreed on in ballistic missile defense.

The TRL-4D LR is the land-based version of a long-range radar Hensoldt also builds for the German Navy, German outlet Sicherheit & Verteidigung reported. The outlet cited Germany's defense procurement office as giving the naval version a range of more than 400 km (250 miles) against air targets. That, it concluded, puts the range well beyond the TRML-4D's.

"The Ukrainian air defence forces urgently need our high-performance radars to help protect infrastructure such as bridges," Dörre said.

Defense Express, describing the same memorandum, tied both the mass deliveries and the joint-operation plan to the TRML-4D. Hensoldt's release names no model for the deliveries and links joint operation to the TRL-4D LR.

Eyes for FREYJA

Hensoldt and Fire Point signed a memorandum on FREYJA at the Eurosatory arms show in Paris in June, with the TRML-4D to play a key role, Hensoldt announced. Fire Point is set to act as prime contractor and hold design authority. Hensoldt is to produce, test, and deliver the radars.

Defense Express expects any study of deployment options to focus on how well the radar detects ballistic missiles and relays that data. Hensoldt has its own unit in Ukraine to work closely with operators, the outlet noted. Earlier, the company began setting up a local hub so Ukraine can service and repair the TRML-4D itself.

Already on duty

Ukraine's military uses the TRML-4D both standalone and as the built-in radar of the IRIS-T SLM medium-range air defense system, Defense Express noted. Hensoldt lists an instrumented range of 250 km (155 miles) at altitudes up to 30 km (19 miles). Defense Express, citing the manufacturer, gives track ranges of more than 120 km (75 miles) for fighter jets and more than 60 km (37 miles) for supersonic missiles.

More radars give earlier warning of ballistic strikes, but they cannot stop them. Until the FP-7.X makes its first ballistic intercept, planned for mid-2027, that job stays with Patriot and SAMP/T missiles. Partners delivered three times fewer air defense missiles in the first half of 2026 than a year earlier, Zelenskyy said on 5 August.

Ukraine is working on a satellite system of its own, something similar to SpaceX's Starlink, Ukrainian President Volodymyr Zelenskyy said on 4 October, Interfax-Ukraine reported. He argued Kyiv should be free to turn Starlink on Russian military targets, warning that China and other states will share comparable satellite technology with Moscow within months. Ukraine's battlefield communications still ride on a network owned by Elon Musk, who has clashed with Kyiv and once limited its wartime use.

Low-orbit satellite internet has turned into a frontline utility that a single company or government can switch on or off, and both armies are now racing to own that link instead of renting it. Control of the network decides whose drones can see the battlefield and fly through the jamming to strike it—leverage Kyiv has gone without while its connection rode on hardware it does not run.

Working on a Starlink of its own

Zelenskyy said there was groundwork in place and that Ukraine was working on a system similar to Starlink. He called it fair for Ukraine to aim Starlink at military sites inside Russia. The timing is the reason, he said: some states will share the technology with Russia late this year or early next, and the Chinese are among them. Moscow is already fielding its own Starlink-style constellation, Rassvet, though for now it reaches Ukraine only in brief passes.

Ukraine's troops and drones lean heavily on Starlink, a network Kyiv neither owns nor controls. Musk has used that control against Kyiv before: in 2022 SpaceX refused a Ukrainian request to extend Starlink over occupied Crimea for a drone strike on Russia's warships, and it has since restricted the network's use for drone operations.

Sanctions, and satellites of its own

Zelenskyy has asked US President Donald Trump several times to sanction the Russian and Chinese companies building Russia's Rassvet network, most recently at the UN General Assembly in New York, he said in a recent Financial Times interview.

Denys Shtilerman, co-founder and chief designer at Ukrainian defense company Fire Point, told the Financial Times in May that the firm had launched two satellites this year and planned dozens more in 2027, aiming to reduce reliance on the US government and Western tech companies. To strike deep inside Russia and gather intelligence, he has said, Ukraine needs its own constellation covering all of Russia.

Ukraine has fired its new Fire Point FP-7 ballistic missile in anger for the first time, Ukrainian President Volodymyr Zelensky announced on Thursday, 1 October.

Kyiv hasn't said what the missile targeted or how much damage it caused. The Wall Street Journal, citing an unnamed source, reported that it struck a target in Russian-occupied Ukraine. Zelensky was ecstatic on social media. "Thank you for the result," the Ukrainian president wrote. "Next up: production. Glory to Ukraine!"

The FP-7 can hit back at Russia, but it can't stop the Iskander ballistic missiles Russia fires at Ukrainian cities. Its twin is meant to. Fire Point is building an interceptor version, the FP-7.X, as the core of Freyja, its bid for a cheaper alternative to the American Patriot, and the company aims for a first ballistic missile interception by mid-2027.

Kyiv drone- and missile-maker Fire Point, most famous for its FP-1 and FP-2 one-way attack drones and FP-5 Flamingo cruise missiles, has been hard at work on ballistic missiles for at least a year. Ballistic missiles can cost millions of dollars per round, making them much more expensive than a $50,000 drone or $500,000 cruise missile.

But the extra expense buys a lot more destructive potential. An FP-1 packs a 60-kg warhead; an FP-7's warhead weighs about 200 kg. While an FP-1 might motor as far as 1,000 km, it's slow and fairly easy to shoot down. An FP-7 possesses less range—up to 250 km under the best conditions—but it streaks through the atmosphere at several times the speed of sound, making it extremely difficult to intercept.

The only Russian air defense systems that stand any chance of swatting down an incoming FP-7 are also among the most in-demand in the Russian inventory and thus the most over-stretched: the S-400 surface-to-air missile batteries.

Ukrainians know better than anyone the kind of damage and terror ballistic bombardment can inflict. Since effectively running out of Patriot surface-to-air missiles earlier this year, Ukraine has been unable to defend itself against weekly Russian bombardment that now usually includes several Iskander ballistic missiles.

The Russian bombardment threatens to disrupt commerce, throttle electricity generation, and grind down Ukrainian morale at a critical juncture in Russia's wider war on Ukraine. Ukrainian troops are holding their own along the 1,200-km front line, but behind the front line everyday Ukrainians are suffering under missile and drone impacts.

That suffering will only get worse as winter closes in, temperatures drop, and the Russians resume intensive attacks on the electrical grid, potentially depriving millions of people of household heating. Ukrainian batteries firing FP-7s can't directly prevent Russian attacks. But they can retaliate for the attacks.

Expect the ballistic tit for tat to intensify. It may not be the first Ukrainian ballistic missile fired in anger: in June, Russia said it shot down a Ukrainian ballistic missile over Moscow, and Kyiv never said what it was. But the FP-7 is the first Kyiv has confirmed using in combat, and it has the range and payload to inflict serious damage on targets inside Russia. But an even more powerful Ukrainian missile, the Fire Point FP-9, is coming soon. It reportedly ranges 850 km with an 800-kg warhead.

The ballistic phase

The FP-7 can smash Russian depots, air bases, and factories in oblasts bordering Ukraine. The FP-9 could wreak havoc as far as Moscow. The only major constraint on the Ukrainian bombardment will be Fire Point's production capacity, and Kyiv's ability to finance that production.

The Ukrainians will be incentivized to produce as many FP-7s—and, later, FP-9s—as possible. The same factories that produce surface-to-surface FP-7s will also churn out a surface-to-air variant, the FP-7.X.

That missile, which is overall similar to the standard FP-7 but includes a sophisticated seeker head, is the main munition for Ukraine's new mostly homemade air defense system being developed by Fire Point and various foreign partners under the auspices of the European missile defense program Freyja.

If the FP-7.X works as advertised and Fire Point can scale production, it could bolster Ukraine's defenses against Russian ballistic missile strikes while the standard FP-7 and its bigger cousin the FP-9 retaliate for Russian ballistic missile strikes.

A new phase of the wider war is about to begin—the ballistic phase, where both sides can pummel the other with hard-to-intercept missiles.

The side that makes the most and best missiles, for offense and defense, will prevail in the coming ballistic fight.
